| Abstract/Contents: | "With the development of existing and new plant growth regulators (PGRs), the turf industry is beginning to rely on them for reasons such as seedhead suppression, reduced mowing frequency, etc. Trinexapac-ethyl and paclobutrazol are commonly used in high maintenance turf areas by professionals because of their effectiveness in reducing biomass production and also enhancing turf quality. These PGRs also reduce internode lengths resulting in a more dense turf canopy that is desirable among the turf industry. Bermudagrass growth suppression with various PGRs has been well documented. Field trials were conducted in 1998, 1999, and 2000 using randomized complete block designs evaluating different rates and timings of trinexapac-ethyl, paclobutrazol, and others to determine optimum results. Plots were maintained as a fairway (0.5 inch) and clippings were caught on a weekly basis beginning 1 wk after treatment. Clippings were oven-dried and biomass was recorded. Data were subjected to analysis of variance and means were separated according to LSD (P=0.05). Trinexapac-ethyl, with repeat applications at 12-16 oz/a, was more consistent at suppressing bermudagrass growth than was paclobutrazol at 24-32 oz/a along with other PGRs tested. Growth suppression was observed with trinexapac-ethyl through 9 wk after initial treatment. Although more effective, quality reductions with trinexapac-ethyl may occur with repeat applications." |
